【摘要】 以NO3-为光催化剂,在紫外灯照射下,对甲基橙溶液进行光催化脱色。结果表明,叔丁醇、甲醇和乙醇对催化脱色反应有抑制作用;KB r和Na2SO4对脱色反应均有促进作用;而且KB r的加入量存在最佳值;Na2SO4的促进作用随Na2SO4的量的增加逐渐增强。Na2CO3的存在对甲基橙的脱色反应没有影响。K2S2O8和NO3-之间存在较强的协同作用;K IO3和NO3-之间存在相加作用;KB rO3和NO3-之间存在拮抗作用。更多还原

【Abstract】 The NO-3 was used to decolorize the methyl orange(MO) solution with ultraviolet radiation.Influence of several reagents on photocatalytic decolorization of methyl orange with NO-3 was investigated.The results indicate that t-BuOH,ethanol and methanol can press the decolorization reaction,KBr and Na 2SO 4 can promote the decolorization reaction,there is an optimal amount of KBr in this case and the effects of Na 2SO 4 increase with the concentrations,while Na 2CO 3 has no obvious influence on the decolorization reaction.The synergy between K 2S 2O 8 and NO-3 is very strong.There is no synergy between KIO 3 and NO-3,while there is inhibitation between KBrO 3 and NO-3.更多还原
